Inventor: TROUGHTON NICHOLAS ARADOR
IPC: C11D3/39
Filed: 1990-05-21
Abstract: Dans une classe de procédés de fabrication d'acides de peroxyde organiques faiblement solubles, l'acide carbonique correspondant est mis en réaction avec le peroxyde d'hydrogène dans un milieu de réaction contenant une forte concentration d'acide sulfurique. La présence de tels composants dans le mélange réactif ainsi que le comportement des composants et la manière dont ils sont mis en contact peut se révéler aléatoire dans les procédés. Dans cette invention, les problèmes d'incertitude sont réduits ou éliminés premièrement par la dissolution de l'acide carbonique dans de l'acide sulfurique concentré, deuxièmement par la formation d'une solution acide de Caro contenant une quantité complémentaire d'acide sulfurique et de peroxyde d'hydrogène dans une fourchette prédéterminée, et ensuite par l'introduction d'une solution d'acide carbonique à un taux contrôlé dans la solution d'acide de Caro, souvent pendant une période allant de 30 à 90 minutes, avec un contrôle de l'agitation et de la température. Les compositions des deux solutions réactives sont précalculées en fonction l'une de l'autre de sorte que la valeur A (rapport du poids de l'acide sulfurique sur le poids combiné de celui-ci et de l'eau) augmente au cours de l'ajout de la solution d'acide carbonique ou bien reste la même ou augmente si la solution d'acide carbonique est relativement moins insoluble. De préférence, les solutions sont formulées pour fournir une valeur de A, à la fin de la période de réaction, qui se situe dans une fourchette d'environ 0,7 à 0,8, à une température d'environ 20 à 45°, la solution la plus soluble se rapprochant de l'extrémité la plus basse de chaque fourchette et la solution la moins soluble tendant vers l'extrémité la plus élevée de chaque fourchette. Le procédé est plus particulièrement adapté pour produire des acides carboniques diperoxy ou des acides mono-aliphatiques faiblement solubles comme l'acide peroxyanoïque ou l'acide diperoxydodécanédiodique ou pour des acides de peroxyde substitués à un groupe aromatique pour
